Merge tag 'iommu-updates-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
- support for interrupt virtualization in the AMD IOMMU driver. These
patches were shared with the KVM tree and are already merged through
that tree.
- generic DT-binding support for the ARM-SMMU driver. With this the
driver now makes use of the generic DMA-API code. This also required
some changes outside of the IOMMU code, but these are acked by the
respective maintainers.
- more cleanups and fixes all over the place.
